How to use the slot finder

Every filter on this page works with the others. Pick a provider, add an RTP range, tick a feature like Megaways or Hold and Win, and the list narrows as you go. If you end up with nothing at all, take one filter off rather than starting over.

• Search is for when you already know the name. Everything else is for when you do not.
• Filter by letter is the quickest route to a title with awkward spelling.
• Order by changes the sort without changing what is in the list.
• Every card shows the RTP we hold for that game, so you can compare before you click.

Open any game for the rest of it: reels, paylines, volatility, maximum win, the studio behind it, screenshots, and the casinos that currently run it.

Where our slot data comes from, and what it is worth

The figures on these pages come from the game providers' own paytables and help files, from the casinos that licence the games, and from playing them. We keep them in one database and correct them when a provider updates a game, which happens more often than you would think.

Two honest caveats, because they matter more than any of the marketing you will read elsewhere.

RTP is not always fixed. A lot of slots ship with more than one RTP setting and the casino chooses which one to run. The same game can pay 96.5% at one site and 94% at another, with nothing on screen to tell you which you are on. Where a provider publishes a default, that is the figure we show. Always check the game's own info screen once it loads, because that is the only place the live number appears.

A published maximum win is a ceiling, not a forecast. A 50,000x max win means the maths allows it, not that anyone has done it recently, or at all.

RTP: what it tells you and what it does not

RTP stands for return to player. It is the percentage of everything staked that a slot is built to pay back, measured over millions of spins rather than your afternoon. A 96% RTP does not mean you get £96 back from £100. It means that across the whole population of players, over a very long run, the game returns about 96p in the pound.

It is still the most useful single number for comparing two games, because it is the only one that describes the cost of playing. What it cannot do is tell you what any individual session will look like. That is volatility's job.

For context, the commonly cited average for online slots sits around 96%, with plenty above 97% and a long tail below 94%. Use the RTP filter to set a floor you are comfortable with rather than chasing the single highest number.

Volatility, in plain terms

Volatility, sometimes called variance, describes the shape of the wins rather than their total. Two games can share an identical RTP and feel nothing alike.

Low volatility

Frequent, modest wins. Your balance moves in small steps and a set budget lasts longer. Good if you want a long session, or you are learning a game before committing.

Medium volatility

The middle ground most big-brand slots aim for. Regular enough returns to keep a session going, with occasional wins large enough to be worth waiting for.

High and extreme volatility

Long quiet stretches broken by rare, large wins. The maximum win figures are usually much higher here, and so is the chance of a session ending with nothing. Bet smaller per spin than you would on a low-volatility game, because you need the spins to reach the feature.

Paylines, ways to win and Megaways

A payline is a fixed pattern across the reels that a winning combination has to land on. Classic slots might have one. Modern ones run to twenty, fifty or more, and you usually stake across all of them at once.

Ways to win games drop the fixed patterns. Matching symbols on adjacent reels pay wherever they land, which is where figures like 243 or 1,024 ways come from.

Megaways, licensed from Big Time Gaming, changes the number of symbols on each reel every spin, so the ways to win change with it, often up to 117,649. It tends to come with high volatility and cascading reels.

Cluster pays drops reels and lines entirely. You win by landing a group of matching symbols touching each other anywhere on the grid.

More paylines does not mean better odds. The RTP already accounts for the pay system, so use the filter to find the format you enjoy, then compare RTP within it.

The bonus features worth knowing

You can filter by any of these. They change how a game plays far more than the theme does.

• Free spins are the most common bonus round, usually triggered by scatter symbols and often carrying a multiplier or an extra wild.
• Hold and Win locks landed symbols in place and gives you a small number of respins to fill the grid. Popular for its steady, visible progress.
• Bonus buy lets you pay a fixed multiple of your stake to skip straight to the feature. It is not available at every UK casino and it is an expensive way to play.
• Wilds substitute for other symbols. Sticky, expanding, walking and multiplier wilds all behave differently, so check the paytable.
• Cascading reels remove winning symbols and drop new ones in, letting one spin pay several times.
• Progressive jackpots take a slice of every stake across a network and pool it. The headline figure is large, the odds of taking it are very long, and the base game RTP is usually lower to fund it.

Choosing where to play

The game is only half of it. Before you deposit anywhere, check the following.

• The licence. Any site serving Great Britain must hold a Gambling Commission licence. You can confirm it on the Gambling Commission's public register rather than taking a footer badge on trust.
• The provider list. If you have filtered to a studio here, check the casino actually carries it. Game libraries change.
• The bonus terms, not the headline. Wagering requirements, game weighting, maximum bet while a bonus is live and the expiry date decide whether an offer is any good.
• Withdrawal times and limits. Easy to ignore until you win.
• The deposit limit and reality check tools. Every UK-licensed site has them. Set them when you open the account, not later.

Are online slots fair?

Results are produced by a random number generator, and at a UK-licensed casino that generator has to be independently tested. The testing houses you will see named are eCOGRA and Gaming Laboratories International, among others approved by the Gambling Commission.

What that certification means in practice: each spin is independent, nothing is influenced by your stake, your history, or how long you have been playing, and the game pays to the maths it was certified against. What it does not mean is that the game is beatable. The RTP is below 100% by design, which is the whole point of the business.

There is no such thing as a slot being due, hot or cold. A machine that has just paid its jackpot has exactly the same chance on the next spin as one that has not paid for a year.

Playing responsibly

Slots are entertainment with a cost, and that cost is the RTP working against you over time. Decide what you are willing to lose before you start, use the deposit limits every UK casino has to offer you, and stop when you reach the number rather than when the balance is gone.
